WOLF, OF DEVILS LAKE, NORTH DAKOTA HAY STAGKER AND LOADER Application filed January 19, 1929. Serial No. 333,645.

This invention relates to handling mechanism and particularly to means for stacking hay in bales and loading the hay, it being understood that the mechanism which Twill hereinafter describe is adapted either for use in the open, in a barn, or on a wagon.

The general object of the invention is to provide a very simple, readily operated and cheaply constructed loader and stacker which may be operated either by motor or by hand power if desiredand which is adjustable to different circumstances of operation.

A further object is to provide a mechanism of this character having very simple means whereby it may be controlled and the boom swung around in a circle and the bale raised or lowered as the circumstances of operation dictate.`

My invention is illustrated in the accompanying drawings, wherein Figure 1 is a side elevation of a mechanism constructed in accordance with my in vention showing the boom in a horizontal position;

Figure 2 is a like view to Figure 1 but showing the boom raised;

Figure 3 is a sectional view through the winding drum and illustrating an elevation of the gears for driving it;

Figure 4 is a fragmentary view of the controlling lever for the winding drum;

Figure 5 is a fragmentary sectional view of the pulley, carriage and latch; y

Figure 6 is a transverse section through i the bracket 35au showing the sliding supporting bar and the shaft and beveled gear carried thereby in elevation. i

Referring to Figures 1 and 2, 10 designates a rack of any suitable character such as a rack upon a wagon or a rack disposed upon the floor of a barn or in any other situation, this rack constituting in a sense the base` of the machine. y This rack may eX- tend out in opposite directions to any extent required and carry the upright stakes 11 at intervals, or the rack may be relatively long and narrow as in the case of the ordinary hay rack.

Mounted upon this rack and supported by means of a supplementary frame as will be laterl described, is a mast 12 preferably composed of metal piping and having a reinforced portion 13 which is preferably of double thickness. The piping is supported in any suitable bearing at its lower end and carries upon it the gear wheel 14 whereby the pipe may be rotated. The pipe is supported within a bearing collar 15 which eX- tends around the thickened portion of the pipe and is disposed to extend downward through a frame 16 to which guy wires or rods 17 are connected which extend upward to the collar 15. p

At its upper end the mast 12 is forked at 18 to receive within the fork the boom 19 which is pivoted to the fork at 20 so that the boom may be swung from a horizontal to an upwardly inclined position. The boom is also composed of metal pipe braced by the tensioned struts 21 which extend longitudinally of the boom and are under such tension as to resist bending strains. The boom projects out beyond the fork 18 at its rear end and carries upon it the pulley 22. Mounted upon the thickened portion 13 of the mast is a pulley 23 and over these pulleys passes the cable 24. By pulling upon this cable as shown in Figure 2, the boom may be raised and by slacking upon the cable the boom may be lowered.

Mounted upon the frame 16 in any suitable manner is a shaft 25 which at one end may carry the driving wheel 26 which as illustrated in dotted lines in Figure 1 may be connected to a motor or engine. This shaft 25 is also preferably formed `at one end with means for receiving the crank 27 as shown in Figure 1 so that the shaft may be rotated by hand, where only one or two bales are to be lifted or the bales are light.`

Loosely mounted upon the shaft 25 is the winding drum 28 shownin detail in Figure 3. `The shaft 25 carries upon it the opposed beveled gear wheels 29 and 30 and for the purpose of driving the gear `wheel 14 and thus rotating the mast there is provided a vertical shaft 31 which its lower end carries a pinion 32 meshing with the gear wheel 14;. This shaft 31 is preferably formed in two sections, the upper section 31a being CFI shiftable laterally and carrying* the beveled pinion 33.

By shifting the upper section 31a lateral- `ly the pinion may be carried into engagethree notches 341? whereby the lever 34 may be held in a neutral position or engaged with either of the gears 29 or o0. The lever may be lifted in order to shift the shaft section to any desired position.V Y Y Mounted upon the shaft 25 and opposed to the inner end of the drurn 29 is a clutch member 36. The adjacent end of the drum is formed with the clutch teeth 37 This clutch member 36 and the drum are recessed to enclose within them the compression spring 38 which urges the drum away from the-clutch member 36. The opposite end of the drum 28 carries upon it the brake disk 39 having a'rim 40 in the forni of a frustrate cone. Associated with this end of the drum is a fixed brake band 41 supported upon the brackets 42 from the frame member 35 and the spring 38 normally forces this brake wheel against the brake band 41 and holdsthe drum from rotation. The drum may bev shifted into engagementl with the clutch member 36 and thereby caused to rotate with the shaft 25 by means of the angularl lever 43 pivotally mounted upon the bracket' 44, this lever 43 being formed at its lower end and shown in Figure 4 as at 45 to embrace thev shaft 25 and bearing against the rounded end of the drum 28.

A cable 46 is attached to the upper end of the lever 43 and passes over the pulley 47 and extends to any desired point so that the shifting of the drum into or out of engagement with the shaft 25 may be accomplished from a distance.

Carried upon the boom 19 relatively close tothe fork 18 is a pulley 48 and slidingly mounted upon the boom 19 as shown in Figure 5 is a carriage 49 supporting the pulley 50. This carriage is normally held at the outer end of the boom by means of a latch 51 pivoted within a block 52 carried upon the end of the boom and urged by a spring 53 into engagement with the carriage 49 to hold the carriage at the outer end of the boom. This carriage is provided with an outwardly projecting arm 54 and hoisting cable 55 is attached to the extremity of this arm 54, which constitutes the extremity of thefboom and extends down around a pulley 56 mounted upon a hay fork 57. The cable then extends upward over the pulley 50 and thence over the pulley 48 and down to the drum 28. The hay fork 57 may be of any suitable construction but is shown in the form of a U-shaped member having its ends harpoon shape so that it may be inserted into a bale or into a mass of hay.

In order to provide means for bracing the mast if desired against extra strain, l provideV the guy rope o'r cable 58 engaged with the upper end of the mast by means of the ring 59 through which the cable passes, this cable being adapted to be brought down and have its lower end pegged to the ground. This cable is to be used as shown in Figure 2 when the boom is disposed vat such an elevation that excessive strain comes upon the mast.

The operation ofr this mechanism will be obvious. Vhen it is desired to raise or lower the hay fork and the hay or other bale engaged therewith, the operator pulls upon the cable 46 which forces the drum laterally into engagement with the clutch member 36 and causes the rotation of the ydrum under power. When the hay fork has been elevated to the desired extent the operator releases the cable 46 and the drum shifts in the reverse direction and its brake rim 40 comes in contact with the brake band 41 and holds the drum in this position. The operator by now pulling upon the rod 34, which may have a cable or auxiliary rod extending outward any desired distance, can rotate the mast under power to carry the boom to any desired position and then the hay fork may be raised or lowered by the means heretofore described. While I contemplate that the mechanism shall be operated-by power, it is obvious that where the bales are light or there are few of them, it may be operated by hand.

The cable 24 may be hauled in-to any desired extent to lift the boom to any desired angle and then fastenedv Vor the cable may be hauled down or slackened as desired to more or less constantly change the angle of the boom if found necessary. This device is particularly adapted to be used in connection with the hay baler shown in my Patent No. 1,691,885 granted on the 13th day of November 1928. v

I do not wish to be limited to its use as it is obvious that it may be used in other situations. The mechanism is very convenient, issimple, may be readily erected, may be made comparatively light and is so' readily controlled that it is particularly Vconvenient. Y

For high wo'rlr, the carriage 49 may be disposed at the extreme end ofthe vboom as illustrated in Figures 1 and 2 but for relatively low work, the carriage may be released from its engagement with the latch 51 and the carriage will then slide back ward to the strut 21L as shown in dotted lines in Figure l and will then operate precisely as before. Thus the device may be used for placing the bales in smaller circles than where the carriage is disposed at the outer end of the boom.
